 Dear Doctor,


 I had a long conversation with
 Dr. Gray about the style of your Plantae Fremontianae,
 and he suggested several important modifications
 in the arrangement of matter. The
 large type of the generic description be objected
 to, and advised the same as the rest of 
 the article, (Pica), making it conspicuous
 however by double leading. This will of
 course reduce the size of the generic names, which
 the arrangement, we concluded to be better thus.
